Serial No.253,282.v

This invention relates to electric lamp fixtures in general and moreparticularly to a therapeutic lamp fixture. v

Therapeutic lamps are often desired to be f used in a position whichisnot only remote from the Anormal position ofthe lamp but which would,in the ordinary yform of lamp, require the lamp to be either removedVfrom its base or the base removed'froin the floor and the standardsupported by some `temporary and auxiliary means. o A l j z It is theprimaryobject of this invention V'to 'provide a construction whereby thelamp may be conveniently adjusted to a practically un-` limited numberof positions without necessitating` the removal of the lamp from itsbaseor the removal of the basey of the lamp from the floor. f l f f It isalso an object of thisvinventi'on toprovide a lamp of the above type andsupporting means therefor which is convenient to manufacture and toadjust. f .f

It is further an object of this invention to provide in` connectionwitha lampk of the above type a sectional standard therefor in'- cludingan adjustable joint for a pair of the sections which 1s provided with alarge clamping surface. f y y It is also an object of this inventiontopro-l vide a lamp of the above character having a sectional standardanda joint for a pair of the sections in which one section is telescopicwith respect to another section and a clamp for adjustably securing thetwo sections to-V v gether without defacing the stem of the formersection. f

Other and further objects ofthis invention Vwill be apparent as the samebecomes better understood from an examination of the specilication andclaims in connection with the accompanying drawings wherein ,l

ing 16 is tted within thecasting 13 andthe upper end of the member12-whereby it may receive the stem 17 of a section 18which risrelatively adjustable with respect to the member 12. The bu'shinglS islongitudinally split by means of a pair of opposite slots 19 extendingdownwardly from the upper edgeof said bushing and dividing the ,upperportion yof the bushing into a pair of semi-cylindrical portions One ofthe portions 21 is in p osition to be engaged by theI inner end of thescrew lwhen the same is turned inwardly for clamping said portionagainst thestem l?. The other portion 21 is brazed or other-vwisesecured to the interior of the castinggl and the member 12. j f Thesection 18 is provided on its upperI end with a pair ofspaced clampingears 21 and j 22 respectively on opposite sides of a disc 23. The disc28 is secured to the lower end cfa curved sectiony 24 of the standard. Ascrew n 25 provided with a manually operable knob 26 extendstransversely through the center of theears 21 and 22 and the disc 23 forrotatably supporting said-disc between said ears and cooperates withsaid knob for clamping said disc between said ears. The ear 22`isdetachable and may be removed byfremoving the screw 25. This. earisprovided with a bi-k furcated lower end cooperating with a lug 27 forpreventing rotation of the ear. This con.- struction l facilitatesassembly and enables the ear Q2 to be clamped against the disc 23 with aminimum of force eXerted on the knob 2G.

The section 24 is in the form of a hollow tubular member the upper endof which is bent approximately ninety degrees from the lower end. Saidupper end is embraced by a casting Q8. The casting 23 like the casting13 is provided with an adjusting knob and screw 29. In this case theupper end of the tubular member 24 forms the bushing and said upper endis longitudinally slotted as at 3l to form two semi-cylindrical portions32 and 33 respectively. The semi-cylindrical portion 32 is in positionto be engaged by the screw 29 and the semi-cylindrical portion is brazedor otherwise secured to the surrounding casting 28. A short section 3ais proi'fided with a stem 35 at one end and said stem extends into theupper end of 'the member 24; within the casting 2S and between theportions 32 and 33. The screw 29 may thus be turned inwardly oroutwardly to clamp or release the stem 35.

The outer end of the section 34 is in the form of a fiat rounded portion3G which is clamped between a pair of ears 37 and 3S. rllhe ears 37 and38 form a part of a bracket 39 which is rigidly secured to the lamp 8. Ascrew 4l extends through the ears 37 and 38 and the portion 36therebetween whereby the section 34 is pivotally secured 'to the bracket39 and cooperates with a wing nut 42 whereby the bracket may be clampedin any desired pivotal rela-tion with respect to said section. The ear37 like the ear Q2 is detachable by merely removing the screw il but isprovided with al lug lL3 extending in a recess 44: in the bracket 39 forpreventing rotation of said ear. Thus the detachable ear Afacilitatesassembly and isfree to move axially with respect to the screw ilpermitting clamping action to be had by a minimum of force exerted onthe screw by the wing nut d2.

It will be observed that the at'oredescribed standard including itsvarious sections and connections therebetween may be adjusted with aminimum of ease to bring the lamp into most any position desired withoutnecessitating removing the lamp from the'standard or removing the baseof the standard from its normal position on the floor.

I am aware that many changes may be made and many details variedwithout. departing from the principles of this invention and I thereforedo not wish to be limited to the details shown or described.

I claim:

1. In a lamp fixture7 the combination of a base, a lamp and supportingmeans therefor connected to said base, the connection between said meansand base including a disc on one of the connected parts and a pair ofclamping ears supported on the other part on opposite sides of said discand an adjusting screw for pivotally connecting and clamping said discand ears together, one of said ears being detachable by removing saidscrew, said ear having a slot near one of its margins, and a lugengageable with said slot carried by said ear supporting part forpreventing rotation of said ear.

2. In a lamp iixture, the combination of a base, a sectional standard onsaid base, one section of which is a stem telescopically adjustable withrespect to a tubular member, a lamp and supporting means thereforconnected to the stem, the connection between said means and stemincluding a disc on one of the connected parts and a pair of clampingears on the `other mrt on opposite sides of said disc and an adjustingscrew for pivotally connecting and clamping said disc and ears together,one of said oars being detachable by removing said screw and being held.against rotation relatively to the part on which -it is supported bymeans of a cooperating slot and lug, one of which is formed on saidsupporting part.

3. In a lamp iixture, the combination of a base, a lamp and supportingmeans therefor connected to said base, the connection between said meansand base including a disc on one of fthe connected parts and a pair ofclamping ears on the other part on opposite sides of said disc and anadjusting screw for pivotally connecting and clamping said disc and earstogether, one of said ears being held against rotation and connected toits supporting part only by cooperation of a lug and a slot one of whichis a part of the ear, said lug and slot :permitting the ear to bemovable toward its opposite ear comparatively freely.

In witness of the foregoing I allix my nature.
